- Attach phone to bow (bracket not included) - Attach phone in vertical position (portrait) for multi-point sight
To build bracket for mounting phone to bow: Bend two metal strips at right angles using a vice (heating metal not necessary).
Tape industrial velcro on the inside bend.
Tape velcro to back of phone and attach to bracket in the same position as a traditional bow sight.
Drill holes in bracket to attach to bow (use a 3/16" titanium drill bit for hole, and a 5/16" bit to bevel the hole).
I used #10-24x1" flat head phillips zinc bolts to accommodate my quiver bracket.
Counter-sink hole before drilling, put some 3-in-one oil on metal strip, then drill very slowly to keep drill bit cool.
File off sharp edges, paint with acrylics, and finish with rust-oleum protective enamel.
